    What's a GeneRIF?
    1. the two PsaE isoforms have distinct functions and we propose that O2 reduction at photosystem I is beneficial for the plant under certain environmental conditions.
      Title: Role of the two PsaE isoforms on O(2) reduction at photosystem I in Arabidopsis thaliana.
    2. The psae1-3 psae2-1 double mutant totally lacked the E subunit of photosystem I but was still able to grow photoautotrophically.
